The invention relates to a method for detecting that the design loads of an aircraft have been exceeded during landing. According to the invention: --in a preliminary step: the load criteria (C1, C2, . . . , Cp) are defined; and the laws of variation of the allowable values (C1ad, C2ad, . . . , Cpad) of these load criteria (C1, C2, . . . , Cp) are determined, as a function of input parameters (P1, P2, . . . , Pn); and --at the moment of landing: the values of the said input parameters (P1, P2, ....

The invention provides a probe for an aircraft including a strut having an interior passage accommodating a plurality of pneumatic lines, a probe head extending from the strut and having at least one inlet opening communicating with the pneumatic lines, a baseplate situated below the strut for attaching the probe to the aircraft, and a manifold situated below the baseplate for communicating with the pneumatic lines, wherein the baseplate is adapted and configured so that the pneumatic lines comm...

A seismic data acquisition system includes a plurality of sensors which are arranged so they can be used to measure translation movements of a medium with three independent spatial components and of the rotation movements around each of the three independent spatial components, thus forming a six-component system.

A nautical instrument that can be repetitively mounted to and removed from a surface within a ship without the use of tools or other instruments. The nautical instrument incorporates a mounting system that achieves slidable locking engagement of the nautical instrument to a bulkhead plate that is permanently secured to the surface of the ship. In one embodiment, the invention comprises: a housing containing a gauge; a back plate connected to the housing and having a rear surface; a bracket assem...

An evolutionary development of my prior inventions into an improved display form, more compatible to the desires of the overwhelming majority of pilots. This new invention is a natural derivative of my (co-pending application for patent, Ser. No. 629,850, file date July 11, 1984 for Bank and Pitch Indicator) and (co-pending application for patent, file number pending, file date Mar. 25, 1985 for Improved Pitch Indicator for Bank And Pitch Indicator). This new display will be composed of a displa...

A method and apparatus are provided for indicating the altitude at which an aircraft should fly so the W/d ratio (weight of the aircraft divided by the density of air) more closely approaches the optimum W/d for the aircraft. A passive microwave radiometer on the aircraft is directed at different angles with respect to the horizon, to determine the air temperature and therefore the density of the air, at different altitudes. The weight of the aircraft is known. The altitude of the aircraft is ch...

Continuous display of pitch attitude beyond normal limits of plus or minus 20 degrees is provided by an extended pitch indicator whose operation is coordinated with a primary pitch indicator which provides pitch information through primary ascent and descent ranges (plus or minus 20 degrees). Operation of the extended pitch indicator is coordinated with operation of the primary pitch indicator in such a manner that the extended pitch indicator is hidden from view during flight maneuvers within t...

A meter face arrangement for use with a cross wind sensor that provides information indicating relative airspeed with respect to a probe, and also the direction of the relative wind, which permits an operator of an aircraft such as a helicopter pilot or an operator of a levitated vehicle or an observer in a ground installation to determine the relative movement of the air and also the relative direction of movement. The meter face is made so that the indicator will visually provide the direction...

An instrumented device for the study of airflow over a structure (10), comprises a support (16) forming a thin plate (24) adapted to be applied and shaped to the contour of a predetermined region of the structure. Connection structure (22) cements a portion of an inner surface of the support to that predetermined region, leaving a space (36) of low height between an inner surface of the plate (24) of the support and that predetermined region. This height is substantially equal to the thickness o...

The invention is a method for determining anemobaroclinometric parameters on board an aircraft. The air speed vector (Vp), the static pressure (Ps), and the impact temperature (Ti) are measured, and the other parameters are calculated on the basis of the aforementioned measurements.
